The standard addressed many problems found in the diverse floating-point implementations that made … See more
The first standard for floating-point arithmetic, IEEE 754-1985, was published in 1985. It covered only binary floating-point arithmetic.
A new version, IEEE 754-2008, was published in August … See moreAn IEEE 754 format is a "set of representations of numerical values and symbols". A format may also include how the set is encoded. See more
Required operations for a supported arithmetic format (including the basic formats) include:

The standard recommends optional exception handling in various forms, including presubstitution of user-defined default values, and … See more
The standard defines five rounding rules. The first two rules round to a nearest value; the others are called directed roundings:

IEEE 754-1985 was an industry standard for representing floating-point numbers in computers, officially adopted in 1985 and superseded in 2008 by IEEE 754-2008, and then again in 2019 by minor revision IEEE 754-2019. During its 23 years, it was the most widely used format for floating-point computation. It was implemented in software, in the form of floating-point libraries, and in hardware, in the instructions of many CPUs and FPUs. The first integrated circuit to implement the d…
